Why is Germanium a metalloid?
As a metalloid, germanium has both metal and non-metal qualities. It also is a semiconductor, which means it has electrical conductivity between an insulator and a conductor. This characteristic has led to it being used in electronics.
What makes germanium different from metals and nonmetals?
Germanium is metalloid, which means it has properties of both metals and nonmetals. Germanium is one of the few elements that expand when it freezes, like water does, according to Chemicool. Others include gallium, silicon, bismuth and antimony.
Is a metalloid a metal?
A metalloid is an element that has properties that are intermediate between those of metals and nonmetals. Metalloids can also be called semimetals. Notice that aluminum borders the line, but it is considered to be a metal since all of its properties are like those of metals.

Is Iodine a metal?
As a pure element, iodine is a lustrous purple-black nonmetal that is solid under standard conditions. It sublimes (changes from a solid to a gaseous state while bypassing a liquid form) easily and gives off a purple vapor. Although it is technically a non-metal, it exhibits some metallic qualities.
Why is iodine not a metal?
Iodine is not a metal , it is a halogen it belongs to the same group of elements such as Fluorine and chlorine. It is commonly found as a water soluble ion. It is not a metal because it is electro-negative while metals are electro-positive .

Is iodine an atom or ion?
Density (near r.t. ) Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.
Is Potassium A iodine?
KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.
Who should not take iodine?
Iodine is POSSIBLY UNSAFE when taken by mouth in high doses. Do not take more than 1100 mcg of iodine per day if you are over 18 years old; do not take more than 900 mcg of iodine per day if you are 14 to 18 years old. Higher intake has been shown to cause thyroid problems in the newborn in some cases.
